Method Detail

delete

public OrchestrateRequest<java.lang.Boolean> delete()

delete(boolean).

delete

public OrchestrateRequest<java.lang.Boolean> delete(boolean purge)

Purge a KV object from a collection in the Orchestrate.io service. This will permanently remove the record from the service, and cannot be undone.

Usage:

 boolean result =
         client.kv("someCollection", "someKey")
               .delete(Boolean.TRUE)
               .get();
 
 

Parameters:

purge - If true, permanently delete the object AND its "ref" history from Orchestrate.

Returns:

The prepared delete request.

get

public <T> OrchestrateRequest<KvObject<T>> get(java.lang.Class<T> clazz)

get(Class).

get

public <T> OrchestrateRequest<KvObject<T>> get(@NonNull
                                      java.lang.Class<T> clazz,
                                      @Nullable
                                      java.lang.String ref)

Fetch an object by key from the Orchestrate service.

Usage:

 KvObject<DomainObject> object =
         client.kv("someCollection", "someKey")
               .get(DomainObject.class)
               .get();
 
 

Type Parameters:

T - The type to deserialize the result to.

Parameters:

clazz - Type information for marshalling objects at runtime.

ref - The version of the object to get.

Returns:

This KV resource.

ifAbsent

public KvResource ifAbsent()

Equivalent to this.ifAbsent(Boolean.TRUE).

Returns:

This KV resource.

                 java.lang.String objectRef)

The last known version of the stored object to match for the request to succeed.

Parameters:

objectRef - The last known version of the stored object.

Returns:

This KV resource.

put

public OrchestrateRequest<KvMetadata> put(@NonNull
                                 java.lang.Object value)

Usage:

 DomainObject obj = new DomainObject();
 KvMetadata kvMetadata =
         client.kv("someCollection", "someKey")
               .put(obj)
               .get();
